Okay im going to get rid of my 305 carb and going to go wit a 350 or 383 heres what i need/

its not gonna be a daily driver jus a hwy cruiser and street racer and no gas mileage is needed and it dosent have to be emmisions legal and its gonna have to be all motor but i plan to put a blower on later in the year. i want something with alot of torque so figure the 383 but i also want it to be able to hit 5or 6k easy not having a redline of 5k atleast 6500 or so/

let me know what you got if you got a 383 or jus a 350 and what yah pushing out horsepower and torque numbers.:hail:

 

alright the first thing you need to decide is what you really want do you want to build an naturally aspirated or blown engine there are two totally different engine internals and complete heads and everything your gonna have to look at one will not usually work with the other you really need to decide what you want to build first then go from there

 

heres what it is my friends lil sis got a 78 TA with a 455 and all the good running 11.003 and i wanna be able to keep up with it while were cruising the hwy i dont wanna get smashed so i was think a big block502 off road motor that goes for 6k might get it done

 

You dont need a BB to beat that time. But here is the thing. YOu want to build the engine to make all the power N/A, but then you talk about putting a blower on it later. You need to build the engine right the first time, or you will be building it again later. As far as the 502, I hope you have some deep pockets. For what you are going to pay for the 502, you could probably build one bad *** blown small block that would do the trick entirely, and save some money.

 

yeah i jus seen some times and wit what motor theres an 383 thats running 12.6 and they said thats there first run ever on a motor thats not tunned.so yeah think im gonna stay wit the SBC not a big blvok but the reason i was thinking a big block kus what size cubic inch motors came in caddys theres alot of them at my local junk yard and im there nephew so im sure i can get a deal. but if the 383 will be cheaper then im gonna go wit that then dont wanna take out a loan/

so what block do yo recomend and 350 like a l98 block or something from the good old days.

 

There are a few things you need to figure out for yourself from reading, before you will get very specific answers from people:-

Carb versus TPI, SR, HSR, MR etc.
N/A versus supercharger, turbocharger.
Budget build vs money not an issue.
Building yourself, paying a shop or buying a 'crate' engine.
Smooth idle vs loping idle
Big block versus small block chevy
Based on second hand block or brand new block
Based on 350 block or 400 block.
And so on and so on.

You've already answered not daily driver, gas mileage not important and emissions not required. Which are all very important considerations.

It comes down to all these above, the compromises you may have to make.

And of course, how much money you wish to spend - remember if you're making serious power you need the transmission, rear-end,exhaust and suspension etc etc to match it.

Best of luck to you in whatever you decide.

 

Edit:- Sorry double post.

 

I am building an engine right now - L98 350 block with a 383 stroke and 8:1 compression because it is fully built for 21 lbs of boost from a D-1sc procharger. It is supposed to push around 550-800 horsepower depending on what we can actually get the boost to. I know its a wide range but 550 is still alot and its not limited to 800 just thats what is most feasable at this point. However, my point is that I am building an engine that will most likely be seeing around 650 horsepower, and spending around $500 on full engine, $4300 on procharger, and about $2000 on prepping the engine for the blower. That is $6800 not including my 12 bolt ($1500) and my transmission (T56 - $1300 built for race). So for a car which is about 3400 lbs. pushing 650 i should be deep in the 9's for about $9,500. If you were to buy a 502 Im pretty sure you spend about the same about and run maybe...11's or 12's. I think the best way to go would be to buy an LS1 (if money isnt an issue) put a procharger on it, build a strong transmission and rear end, maybe a mini tub and run as much power as you can without a blower while keeping in mind it is a blower motor. Then put the blower on it and make all kinds of crazy horsepower. Or you can go the way of the blown 400 block...those make a ****load of power too. Anything you look into I suggest building a blower motor. Why? I really dont know... they always seem to make the most horsepower. A procharged Nova with a 427 and running on pump 92 octane runs mid 8's. I suggest building a blower motor.

 

okay im going with carb seeing as i (think) its cheaper and i know alot of old school guys to help me tune if if i happen to need some help.its going to be a used block but get everything checked out so that its poerfect and im build it my self and its not really a budget build but i dont poop mony soo yeah.gotta get the lopey idle um i wanna build it up to be a n/a for now so when i get the money i can jus put a supercharger on it and not have to worry and pray that nothing blows.

 

The only downside to building it like that, is that until you add the supercharger or turbo, the engine isnt going to perform that well.

 

yeah if you build it to accept one of those your gonna have a lower compression engine that isnt going to perform very good

 

is there anyway that all i would have to do is just change heads for when i get the supercharger.

 

if it were me i would find out what the engine specs need to be for the supercharger then build it to the maximum requirments ....thats just me thou
